BBC Thyristor drive, 7.5kw spindle motor 0-6300rpm
Was operating the machine the other day making a cut, hit stop and once the spindle was stopped I could hear an unusual noise. There is a growl in the motor even while it is stopped. The noise stops when the system is disabled but returns when the system enable button is pushed. It seems to be electrical noise in the motor armature as it goes away if I disconnect the armature power plug. Spindle will turn when started but does not sound good.
I will post a list of everything I've tried so far but was hoping someone would jump in and say: Oh yeah! I know exactly what that is, here's what you need to do to fix it.
